One idea could be to get him a copy of the book "Les Misérables" by Victor Hugo. You could also get him a DVD or Blu-ray of the musical or movie adaptation of the story. Another option could be to purchase tickets to see a live production of Les Misérables in his area, or even plan a trip to see the show together. For a more personalized touch, you could create a Les Misérables-themed gift basket with items such as a Les Misérables soundtrack or sheet music, a t-shirt with a quote or image from the story, and a mug or water bottle with the show's logo.
Or you can get him a star map with an important date you share.
